[PATCH v2 1/8] um: allow disabling NO_IOMEM

[Johannes Berg <johannes@sipsolutions.net>]

From: Johannes Berg <johannes.berg@intel.com>

Adjust the kconfig a little to allow disabling NO_IOMEM in UML. To
make an "allyesconfig" with CONFIG_NO_IOMEM=n build, adjust a few
Kconfig things elsewhere and add dummy asm/fb.h and asm/vga.h files.

Signed-off-by: Johannes Berg <johannes.berg@intel.com>

v2: use asm-generic for fb.h and vga.h
